I talked to Scott Placke, OEM Business Development Manager of Parts Express, about offering a discount for group build participants who order an entire kit package. The package includes everything needed to build the line arrays except the wood and glue. It incudes the following:

sixteen #295-301 midwoofers
two #264-578 Vifa DX25 tweeters
two #260-304 bi wire speaker terminals
one pkg #081-435 3/4" #6 driver mounting screws
four #260-411 4" ports
one pkg #095-282 solderless terminals
one pkg #095-286 solderless terminals
one roll #260-540 speaker gasketing tape
one 50ft roll #100-116 speaker wire
crossover parts to be determined

The discount for participants in this group build will be 25% off the regular price. I haven't calculated the total yet because we still need to design the crossover and specify values, but the regular price for everything except the crossover parts would be $331.43. With the discount it comes to $248.57.

Special thanks to Scott and other members of the management at Parts Express. Good folks to do business with!
